SPEIFICATION forming' part Of Letters Patent 0.l 728,368, datedlVIay 19, 1903. Application iiled August 1l, 1902. Serial lim-1119374. (No model-r) j also means for raising and loweringthe same,Y

the features of which will be Ymore fully set forth in the descriptiou'ofthe accompanying drawings, forming a part of this specification,

in which- Figure l is a perspective View of a shaper with my improvement attached, Fig. 2 is a front elevation of a section of table and its support. Fig. 3 is a side elevation of Fig. 2.

A represents the base of the frame, and B the column of the shaper.

C represents the carriage-bed, D the toolcarriage, which is reciprocated on its bed byY mechanisms in the usual manner with crank- Shapers. On the front of the column I have provided ways E, to which is jibbed a vertically-adjustable carriage F. To this carriage is adj ustably secured a table' G, which is of the usual construction. The vertical carriage is raised and lowered by a sorew-rod I. The screw-rod is revolved by crank and miter gears in the usual manner. (Not shown in the drawings.) These parts are of wellknown construction. Y

The vertically-adjustable carriage F is provided with slide-plates L, to the lower end of which are rigidly secured the bracket-arms L', which project laterally forward approximately to the center Vot' the table.l These slide-plates L, being integral with the carriage F, have their inner face planed flush with the inner face or side o'f the carriage, andtherefore rest and slide upon the ways E of the column,'thus inallyimparting the strains to said ways.

M represents a boss or hub on the front end of the bracket-arms. N represents a screwrod passing through a bore in said boss.

ot represents a set-nut having threaded ention.

gagement ,with the screw rod N. b represents a similar set-nut having threaded engagement with said screw-rod. v

O represents a rail which is stretched across the table G, on which the table rests and slides. Screw-rodsN have threaded engagement withthe said support or rail O. When it is desiredto adj usty the rail or support O, one of the nuts may be slackened and the other nut turned to raise or lower the screwrod as desired. Both screw-rods are of the same construction and adjusted in like manner. The table G has two supports upon the crossways ofthe carriage F and upon the bridging rail O, adj ustably supported upon the sliding brackets. By this construction the rail .which supports the front end of the table is rigidly held in position and. may be adjusted to secure the proper table-level, and the table is supported approximately vertically under the center of the vise P, in which is clamp-ed the work, giving a rm vertical support and preventing tremors, thereby Obtaining a uniform cut and preventing vibra- The table can be readily adjusted v'at anytime to an exact level position. It will be observed that-these bracket-supports-for the table are raised andlowered with the table, and when the adjustment is once obtained it is not disturbed byfthe movementfof. the

tablelaterally or vertically. 1

, Having describedzmy invention, I claiml. A shaper provided with fverticalways,

a'carriage provided'iwith slide-plates engaging said ways, atablesupported bysaidcar- .riage,forwardly-projectin g brackets on the slide-plates, and a cross-rail on said brackets forming abottom support for said table, substantially as described.

2. A shaper having vertical ways, a carriage provided with slide-plates engaging said ways, a table primarily supported by said carriage, brackets secured to th'eslide-plates, adj usting-bolts in the ends of said brackets, and a cross-rail engaged by. said'bolts and forming a secondary adjustable table-support, substantially as described.

3. A shaper having vertical guideways, a carriage having integrally-formed slides engaging said ways, atable primarily supported by said carriage, forwardly-extending brack- Io by the said cross-slide of the carriage and the cross-rail of the brackets, and means for adj ustin g the said cross-rail, whereby the table is adjustably supported by the carriage, substantially as described.

In testimony whereof I have hereunto set I5 my hand.
